Sixty five years ago today, the first newspaper accounts of the Electronic Numerical Integrator And Computer hit newsstands.

From the Feb. 15, 1946 New York Times, a page one headline reads: ‘Electronic Computer Flashes Answers, May Speed Engineering’ and its true power is being said to have introduced the modern computer.

Below, we share 10 things about the ENIAC that you really ought to know.

Listen to yesterday’s Radio Times show on the super computer’s debut:
Listen here.

The ENIAC today: modern images

  1. “The ENIAC was the first computer built to take full advantage of electronic processing speeds and to ‘think’ for itself using conditional branching and nested subroutines.” ..Being entirely electronic and credited as introducing the modern, computer industry made it stand apart as well.
  2. The ENIAC was first made public on Friday, Feb. 15, 1946, not, as others have suggested Feb. 14, as confirmed by Philadelphia magazine. (The press release was distributed Feb. 14, as noted on Radio Times)
  3. The ENIAC vision is largely credited to physicist John Mauchly and young engineer J. Presper Eckert, through U.S. Army experimental funding MORE ORAL HISTORY
  4. The ENIAC belongs to the Smithsonian, though small pieces are on loan at the University of Pennsylvania, in Minnesota and elsewhere MORE
  5. “Mauchly and Eckert, went on to create UNIVAC, the first programmable computer designed for business applications.” MORE
  6. “Originally designed for the production of ballistic tables for the Second World War, the machine was not completed until after the war ended. It was widely used for scientific computation until the early 1950s” MORE
  7. Who gets credit? “…With the advent of everyday use of elaborate calculations, speed has become paramount to such a high degree that there is no machine on the market today capable of satisfying the full demand of modern computational methods.’ - from the ENIAC patent (U.S.#3,120,606) filed on June 26, 1947.” The patent was later invalidating by a legal rebuke.
  8. By the Numbers: “The ENIAC contained 17,468 vacuum tubes, along with 70,000 resistors, 10,000 capacitors, 1,500 relays, 6,000 manual switches and 5 million soldered joints. It covered 1800 square feet (167 square meters) of floor space, weighed 30 tons, consumed 160 kilowatts of electrical power.” MORE ENIAC could hold 20 10-digit numbers… you could park a school bus inside the computer MORE
  9. A Quick End: By March 1947, a new electronic super calculator was touted as “capable of making the Army’s world-famed ENIAC look like a dunce” — A series of variations, like the BINIAC followed. “At 11:45 p.m., October 2, 1955, with the power finally shut off, the ENIAC retired.”
  10. A group of female ‘computers’ was instrumental in the ENIAC’s foundation and a documentary focused on their role in the broader World War II fight
